I hadn't thought of a leak in the hard line. I'll have to try to inspect
that.
I've thought about one of those Eezi-Bleed systems. This is probably the
perfect time to get one. I put those SpeedBleeder valves in to make
bleeding easier, but after all the pedal pumping this time around, I'm ready
for something more automated.
